This file type includes high resolution graphics and schematics when applicable. When designing a control system, where the safety system is to be networked, where would you start? To understand the ...

Penn investigators are the first to observe and measure the internal motion inside proteins, revealing how this affects their function. This overturns the standard view of protein structure-function ...

Rotary molecular motors whose motion is controlled by light have been a topic of research for some time, with potential applications in synthetic mechanical systems and nanoactivation. Their ...
